Overview
The LGR46-001 is a temperature data logger for real-time monitoring and a posteriori recording. CE certified and designed for industrial monitoring applications.

Operating modes

• Monitoring — Sends measurements in real time to a PC. If a measurement is not received, it is stored in internal memory and forwarded later.
• Recording / retrieval — Logs measurements to on-board memory; users can download the full history to a PC.

Main features

• Measuring range: −40°C to +100°C
• Accuracy: ±0.3°C
• Resolution: 0.1°C
• Certification: CE
• IP65 aluminium enclosure (4 mm) — tightness valid only if probe and antenna seals are properly tightened
• Includes ½ wave antenna and SMA RF antenna connector
• Power supply: AA Lithium Thionyl battery (included) with plug-in connector
